Subject: [PATCH 1/2] ath10k: Try to get mac-address from dts

Most of embedded device that have the ath10k wifi integrated store the
mac-address in nvmem partitions. Try to fetch the mac-address using the
standard 'of_get_mac_address' than in all the check also try to fetch the
address using the nvmem api searching for a defined 'mac-address' cell.
Mac-address defined in the dts have priority than any other address found.

Tested-on: QCA9984 hw1.0 PCI 10.4
